2. * Social modeling for children with Asperger’s * Direction taken from usability testing * Tutorials to support first-time users * Clarify button names

3. * Animation * Practical considerations * Functional considerations * Attract attention * Engage learners * Sustain motivation * Reduction of extraneous cognitive load

4. * Animation – Research is inconclusive * Ayres et al. identify 2 characteristics * Information is transitory * Animations are a series of successive elements * To offset these characteristics: * ‘tracing’ – leaving information on the screen * Build in user-control

5. Objective of using voice–overs/ sound and text:  to enhance the experience.  to engage and catch the user’s attention. Rationale: Some Advantages revealed by Research …. * “In contrast to print and audio comparisons, which generally reveal no advantage for dual over single presentations, studies show that adding pictures to print or audio generally increases learning” (Nugent, 1992)  A dual modality presentation improves user comprehension and retention.

7. * “Flexibility is extremely important to system use since different users may require different degrees of support” ( Sipior and Garrity, 1992) * A mix of audio and visual components improves attributes such as perception, attention, comprehension, and retention. * Research also revealed some Disadvantages * “a special consideration for video (and spoken audio) is that any narration may lead to difficulty for international users as well as for users with a hearing disability” (Nielsen, 1995) * Decision made: * a combination of voice and * use of simple text along with graphics and icons. Text and Voice Voice Text

8. * Facilitate learning rather than distract * Pick & use 1 or change * This text is for a place holder

9. * Episodic nature of memory – Mayes & Roberts (2001) – visual information most salient * Optimal web video episode length – Nielsen (2005) - keep it short, less than one minute * Google Sketchup and Adobe tutorials – one to eight minute lengths * Czerwinski & Horvitz (2002) – let a previous task item fade from memory before introducing a new one * An issue of length or amount of information required to perform a task?

10. * Usability testing * Parallel designs * Static graphical/textual presentation? * Dynamic animated – with graphics, voice, text * Test efficacy of learning with mock-up * 3-5 Users * Iterative design

12. * Trial 1 – Stop Action Animation Trial 1 – Stop Action Animation * Trial 2 – Animating ‘Jings’ Trial 2 – Animating ‘Jings’ * Trial 3 … Word, Jing, PinPoint, Camtasia - final? Trial 3 … Word, Jing, PinPoint, Camtasia - final?
